NavigationBar bar, tint, and title text color in iOS 8

The background text in the status bar is still black. How do I change the color to white?

// io8, swift, Xcode 6.0.1 
override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.navigationBar.barTintColor = UIColor.blackColor()
    self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orangeColor()]

}
